Sort of OT, but my FVD Sport Exhaut is exactly as you described here...^^^ If you are not used to it, it can be a nuisance. I've had worse and love the way it sounds outside as I finally got to hear it drive down the road....the way a Porsche is supposed to sound

 

I think that is the resonance point of our engines. Gotta live with it if you want loud. But it sounds great loud.

 

It's funny, my 86 930 had a B&B triflow exhaust on it with a 4in single tailpipe and never had any resonance or drone.

 

I wonder how the drone is on the 996/997 GT3's with single exit loud exhaust. Maybe there is something to it. Unfortunately not much engineering goes into the sound factor of these exhaust systems, it's all about flow. I modified a Fabspeed Gen 1 and it flows the same now, but the drone is about half as bad as it use to be. I did it by removing the old mufflers which were nearly 24 inches long each(straight through resonator type), put two 9 inch race mufflers in place of each single unit for a total of four, 2 on each pipe. I then cross connected the two pipes in the middle between each muffler with a flexible connection. This balancing tube does make a difference. Sound is much better and drone is far less. But it is expensive to do, and I paid a lot. In the end it sounds great. I may eventually go to a quieter exhaut b ut till then this one will work.

 

I would love to have an exhaust that sounds like mine, but with no drone or resonance...can you say perfect world? I wish there were more people around that we could just trade exhausts for a week or two?

 

yup, the perfect TT exhaust has not been invented yet, but there are some great ones and some really good custom ones. What kills me is the high cost of tubing and welds $5k just seems crazy for any exhaust.

And when shopping around, youtube videos are such crap quality that you really cannot make a decision based on that. You have to listen to it in person.

 

Yup. As soon as I get a lift, gonna start fabbing my own. It'll be a while though...

 

the fabspeed looks to be a straight pipe with a small resonator and added exhaust length from the "crossover."

some have run straight pipes and claimed that their cars have felt slower after install.

wonder how fabspeed claims the highest hp gain while those who run straight pipes are feeling losses...the only thing that changed was the exhaust length?

and we need a video!

 

Please explain the pros/cons

 

just came back from another night drive
the car is shooting blue flames like no tomorrow
i love it

 

that was the fill in the glass packs burning
